Lighting level requirements strongly depend on type of sport and competition level (lighting classes). Maintained horizontal or vertical illuminance (Eh and Ev) are contained in table to table. These values primarily factor in athletes’ visual needs. Beyond that, lighting requirements posed by national or international sports associations (see also table), particularly for top-level sports events, must also be considered. Examples for such requirements deviating from EN 12193 are also contained in table to table.
From the athletes’ but mostly the spectators’ point of view, a minimum level of vertical illuminance must be generated, at least 30% of the horizontal level (see also chapter "Spatial lighting, direction of light, modelling").
